Application filed January 10, 1927. SerialNo. 160,169.

This invention relates to a machine for the production of barrel linings such as are shown in my co-pending application Serial No. 38,700, filed June 22, 1925. My mproved barrel lining has a body. portion which is longitudinally creped so that the lining can readily accommodate itselfto the shape of tl1e barrel, and this body portion is non-stretchable longitudinally so that it is more or less stifi in the direction of its length and will hold its shape and position within the barrel until the lining is filled with the contents. One end, at least, of the barrel lining is rendered flexible in all directions by double creping it so that the end which is thus double creped may be readily folded over. If desired, the lower end of the lining may also be rendered flexible in all directions as well as the upper end which is to constitute the mouth.

The aim of the present invention is to provide an improved practical machine for economically producing barrel linings of this kind.

In the accompanying drawing, wherein I have shown, for illustrative purposes, one of the many embodiments which the improvements of the present invention may take:

Figure 1 is a plan View of my improved machine;

Fig. 2 is a side View thereof;

Fig. 3 is a detail partial View on an enlarged scale of the crinkling or scraper blade;

Fig. 4 is a front view of the blade looking in the direction of the arrow 11 of Fig. 3; and

Fig. 5 is a view showing a barrel lining such as disclosed in my said application Serial No. 38,700.

Referring to the drawings in detail, the frame of the machine may be of any siiitablc construction, but it is here illustrated as having two side frames 12 and 13 tied together by braces or rods 13*. The roll of paper 14 is supported'on a shaft 15 journalled in suitable brackets located at one end of the frame. A drag is exerted on the paper roll by means of a strap 17 carrying a weight 18, the strap being supported by arod 19. p

The paper web 20 is drawn forwardly over a roll 22'fron1 which it passes downwardly into a'tank 24 and under rolls 23, 23. The water in this tank may be heated by steam coils 25. The wet paper then passes upward- 1y, as at 26, and onto a cylinder 27 upon which the ere-ping and corrugating operations are performed, as hereinafter described more in detail. The cylinder 27 is fixed to a shaft 31 supported in suitable brackets 32, 32. The shaft 31, together with the cylinder thereon, is driven in a clockwise direction, referring to Fig. 2, from a drive shaft 35 through a pinion 36 and gear 37 This drive shaft is'journalled in suitable bearings in the top of the frame and may have a drive pulley 38. The cylinder gear 37 also meshes with a gear 41 fixed to a shaft-42 journalled in suitable rocking levers 43, 43 which are pivoted to a shaft 45. On this shaft 42 is a rubber faced roll 47 which is pressed against the paper, as the paper passes between it and the cylinder, by means of springs 48. This roll 47 is substantially 'coextensive with the crinkling cylinder 27 and serves to squeeze excess water out of the paper and cause the paper to adhere firmly to the crinkling cylinder as it is carried against the doctor blade 50 supported at the proper angle to the cylinder in the upper ends of the brackets 32, 32. After the paper is crinkled, as hereinafter described more in detail, it is carried away from the machine by the belt 51.

In accordance with the present invention, the crinkling cylinder and doctor blade are so constructed and arranged that the paper web is single crinkled, as at 52, for a substantial portion of its width, and at least one marginal or edge portion of the web is corrugated in the direction of the length of the web and is cross crinkled so that the edge or margin, or edges or margins, as the case may be, are flexible and stretchable in all directions. In the present instance, where- ,in I have shown a machine whereby the barrel linings produced are flexible in all directions at both ends, as at 53, the cylinder has, at each end, annular or circumferential corrugations, and between these corrugated portions the cylinder is smooth. The corrugated portions are designated by 27%, and the smooth portion by 27'. The cylinder 27 is preferably made of chilled iron but may be made of any other suitable material. The blade 50 is provided between its ends with a continuous or unbroken crinkling edge 50 which is co-extensive with the the smooth portion 27 of the cylinder, and the doctor bottom faces are grooved, as at 50.

The operation of the machine is briefly as follows: The paper is drawn through the tank 24 and onto the crinkling cylinder against which it is firmly pressed by the rubber faced roll 47. The roll 47 presses the paper into the grooves of the corrugated portions of the cylinder whereby the marginal edges of the web are longitudinally corrugated. The cylinder carries the paper up against the doctor blade with the result that the .web is crinkled throughout its width. The marginal portions of the web are thus double crinkled, so to speak, that is they are rendered elastic and flexible in all directions, and theibody or central portion of the web is single crinkled.

In Fig. 5, I have shown, by way of illustration, one form of barrel lining which may be made .by the use of the present machine. In this instance, the lining is shown as-having both ends double crinkled, but it is'within the spirit of the invention to double crinkle but one end and, preferably, that end which is to cover the mouth of the barrel in which the lining is to be positioned. A barrel lining of this sort is relatively stifi' in its body portion so that it will retain its shape when placed in a barrel until it is filled and, since the end portions are flexible in all directions, they may be readily folded over. The body portion of the lining may expand radially or laterally so as to take the form of the barrel when the lining is filled.

- As many changes could be made in the ter contained in the above description or tended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
